Title: Error propagation processor
Inventor: AWATA YOSHINORI
IPC: H04N1/407
Filed: 1997-02-04
Abstract: PROBLEM TO BE SOLVED: To prevent the increase of a circuit scale, to reduce the circuit scale and to speed up a device by calculating a quantized error at the time of executing linear quantization in an error propagation processing by means of an arithmetic processing from input data. SOLUTION: Input data 2AH is eight bits binary, is expressed by 00101010b and the highest bit is '0'. Thus, a selector 34-3 selects the output of a selector 34-1. A comparator 33 outputs an output value '1' since the high-order four bits of input data 2AH matches a quantized result calculated in a quantization means 2. The selector 34-1 receives it and selects the output of a subtracter 32-1. Since the input B of the subtracter 32-1 is 22H obtained by repetitively connecting the high-order four bits of eight bits input data 2AH, it is subtracted from input data 2AH and 08H is outputted. The output result is generated only in the range of necessary bit width -8 to +8 and it is dealt with five bits data. Since the selectors 34-1 and 34-2 select the output of the subtracter 32-1, 8H becomes a quantized error calculation result.

Title: Fm multiplex broadcast receiver
Inventor: ITO HIDEKI
IPC: H04B1/16
Filed: 1995-01-17
Abstract: PURPOSE: To ensure the effective use of a memory so as to evade such a case where the data stored in the memory are erased by mistake or overflow when the multiplex data obtained by receiving and demodulating an FM multiplex broadcast is temporarily stored and shown on a display. CONSTITUTION: A processor 17 reads out the multiplex data on the FM multiplex broadcast signals under reception and temporarily stores them in a memory 18. At the same time, the processor 17 extracts an enterpriser number out of the additional information on the FM multiplex broadcast signals and stores it in a work memory 23. When an operation part 19 is operated and a receiving station is changed, the enterpriser number of the new receiving station is extracted. If this enterpriser number is coincident with the old number stored in the memory 23, the same enterpriser is decided and the reading of the multiplex data is carried on. If no coincidence is confirmed between both numbers, the multiplex data stored in the memory 18 are erased and the reading of the new multiplex data is started.  The data stored in the memory 18 are held as they are when another audio source such as an AM broadcast, a CD or a tape, etc., is selected at the part 19. However, these data are all erased when a power supply is turned off.

Title: Delivery control method in ink jet recording head
Inventor: KOITABASHI NORIFUMI
IPC: B41J2/125
Filed: 1992-02-07
Abstract: PURPOSE:To make a delivery amount constant under control independently of a delivery port area of a recording head even with a temperature change of the recording head by a method wherein in accordance with the delivery port area of the recording head, a modulation factor of a throw-in energy is changed to be optimum. CONSTITUTION:A drive signal to be applied to a heating element for conducting one delivery action is composed of a plurality of signals. A delivery amount is controlled by modulating the waveform of a preceding signal of the drive signal. Namely, a plurality of drive signals are obtained by dividing the drive signal in a pulse form into two pulses. Pulse widths P1, P3 of division heat pulses and an interval time P2 are determined by times T1-T3. A drive voltage Vop represents an electrical energy required for an electrothermal energy conversion body to generate a thermal energy in ink in an ink liquid path by the application of the voltage. In a division pulse width modulation drive method, pulses are successively applied with the widths P1-P3. A pre-heat pulse is a pulse for controlling an ink temperature in the ink path. The value P1 is determined too small to produce a bubble in the ink.

Abstract: PURPOSE: To prevent the noise voice when turning on power from being generated. CONSTITUTION: The reset signal of 'H' level outputted by a control circuit 21 at the time of power on is inputted to respective bases of NPN transistors 40, 41 and then voltages between bases and emitters become equal to or higher than a prescribed value and collectors and emitters become short-circuited and then collectors become the same potentionals with the ground. Consequently, even though noise signals are generated from amplifiers 37, 38, the noise signals fall down to the ground and signals are not inputted to a right channel output terminal Tr and a left channel output terminal Tl.  When a prescribed time has elapsed, the reset signal is turned to 'L' level and when voltages between bases and emitters become equal to or lower than the prescribed value, collectors and emitters become open circuited and then signals from amplifiers 37, 38 are outputted to left and right channel output terminals Tr, Tl.

Title: Refractory mold for padding metal

Filed: 1997-01-21
Abstract: PROBLEM TO BE SOLVED: To solve such problem as the lowering of water cooling efficiency and the abnormal erosion of a refractory by arranging a material having high erosion resistance on the interface between the molten metal surface and the solidified surface and a material having high heat conductivity on the solidified surface. SOLUTION: As the material 1 having high erosion resistance, a refractory aggregate of 10-30wt.% at least one kind of natural graphite and artificial graphite and the balance Al2 O3 , MgO, ZrO2 and SiC, etc., is used. As the material 2, having high heat conductivity, at least one kind of the natural graphite and the artificial graphite of 100wt.% is sued. Organic binder is used to each material and bonded and reduction- fired. Two materials are integrally formed with a hydrostatic press and thereafter, the reduction-firing is executed. Since the graphite has difficult-to-wet with the molten metal, it shows such large effect as to restrain the infiltration of molten metal. Further, since the graphite is extremely high heat conductivity in comparison with the other refractory aggregates, it is said that the graphite is an effective raw material as a refractory mold.  However, this graphite has such weak pt. as to easily melt with an iron and then, the graphite content in the refractory on the molten metal surface is necessary to consider.
